USER MANUAL
GENERAL
Pego EASYSTEAM sunk-electrode humidifiers are the latest family of humidifiers to be released
onto the market: they are characterised by outstanding completeness of performance and extremely
simple maintenance.
The range includes 3 Kg/h and 6Kg/h humidifiers with single-phase power supply and 6 Kg/h, 12
Kg/h, 24 Kg/h and 48 Kg/h humidifiers with 3-phase + neutral power supply; they all feature
proportional control mode (with 4-20 mA, 0 – 10 V signal) or a simpler ON/OFF control mode.
EASYSTEAM humidifiers feature software with an extensive programming range, full
personalisation and completely automatic operation
This means that the user can set steam output to maximum or some intermediate percentage,
regulate de-concentration emptying frequency or have all the water emptied automatically when the
machine has been idle for a set time.
The EASYSTEAM line also features a display that shows real-time room humidity, the current
being absorbed by the electrodes, working hours, various warnings/alarms, water filling/emptying
status and a full range of user-friendly programming parameters.
EASYSTEAM humidifiers also incorporate a buzzer to warn the user of any faults; the internal
software evaluates the seriousness of the problems and shuts down or continues steam generation
accordingly.
A key advantage of the EASYSTEAM range is that the cylinder with the stainless steel electrodes is
easily changed when normal wear makes such replacement necessary.

OPERATING PRINCIPLE
The sunk-electrode humidifiers in the EASYSTEAM range use the conductivity of potable water to
produce steam by boiling.
The cylinder electrodes are sunk in the water: a current is generated between the electrodes and this
heats the water to boiling point.
Current intensity (expressed in amperes) varies according to the quantity of in-cylinder water that is
in contact with the electrode surfaces and the conductivity of the water.
The electronic controller measures, via an amperometric transformer, current intensity and controls
the water inlet valve (to raise the water level) or the discharge valve (to lower it) accordingly. This
system is fully automatic.
Combined use of the microprocessor and a humidity sensor also makes it possible to effect
proportional control: this optimizes water and electricity consumption according to required
humidity levels.
In addition to ensuring that the humidifier works properly the discharge pump also empties the
cylinder completely when the unit had been idle for a set time: this prevents limescale or other
particles created during the boiling process from depositing.
The humidifiers in the EASYSTEAM range are fully automatic and require only replacement of the
cylinder when the electrodes are worn.
The diagram below illustrates the operating cycle.
Page 9
USER MANUAL
The supplied steam is managed proportionally to steam production request that the electronic
control computes on the basis of functioning selected between the available five described at
chap. 2.4. The minimum steam
supply is fixed at 20% and it is
managed by an activation
hysteresis; the maximum
supply obtained with the
maximum steam production
request, corresponds to first
level variable set percentage
(Pr). For example if the steam
production percentage Pr, on
ES6 humidifier that produces
6Kg/h of steam, is set to 100%,
the maximum supply will be
6Kg/h; but if the maximum
supply will be 3Kg/h.
To ensure proper humidifier performance use only mains drinking water; this is because it
is free from any harmful content and is compatible with the conductivity range needed for
optimal humidifier performance. Note that in some areas mains water may be unsuitable for optimal
performance owing to very low conductivity or very hard or too much aggressive; the following
table summarizes the parameters required for correct humidifier operation.

* Stated conductivity refers to water at 20° C; bear in mind that conductivity diminishes as water
temperature falls and so water may not be very conductive in winter when mains water is
particularly cold.
To avoid this inconvenience, diminish the produced steam percentage described in chapter
3 PROGRAMMING of this manual.
Do not fill the humidifier with water from wells or water that has been treated with
osmosis/demineralising/softening purifiers.

ES SERIES HUMIDIFIER ELECTRICAL POWER CONNECTIONS AND
SECURITY
Connect power supply to the humidifier terminal block linking 230V to R and N terminals
for single-phase models and 400V + neutral to terminals RST and N for 3-phase models.
It is mandatory to connect the terminal marked by the yellow/green and by PE mark to
power supply earth. If necessary, verify the efficiency of the ground system.
Leave the bridge between terminals 60 and 61 or change it, if necessary, with an emergency
normally open contact.
Terminal blocks 62 and 63 are predisposed for fan unit power supply, in case you install that, please
refer to the user manual attached to the fan unit.
ES AND OEM SERIES CONTROL SIGNALS AND SENSORS CONNECTIONS
Humidifier works in five functioning modes set by software parameter S9, described at chap. 3 and
by specific electrical connections.
Moreover it is required the enabling of digital input terminal blocks 1 and 2 on 100 Master card for
all functioning modes. (in case it’s unnecessary using of external enabling just make bridge on
terminal blocks 1 and 2 on 100 Master). If enabling is missing the display will show OFF alternate
to normal visualization.
Below description of specific connections for each functioning mode.
In case it’s needed to connect 4-20mA probes not supplied by PEGO S.r.l. please call
the technical dept. to verify hardware compatibility of the probe with humidifier.
- ON/OFF MODE:
This kind of functioning allows steam production in only 2 modes: total lack of production or
production at maximum. Enabling is generally provided by a free-voltage contact coming from
an electrical panel controlled by a humidity sensor. To set the second level variable S9=0 and
connect the enabling (normally open free-voltage contact) to terminal blocks 1 and 2 on 100
Master.

USER MANUAL
- PROPORTIONAL mode with 0-10Vdc reference signal:
This kind of functioning allows steam production proportionally to reference signal 0-10V.
Example: a 6V reference signal will lead humidifier to produce 60% of steam referring to
software variable Pr. So if Pr= 70% will be 42%. To set the second level variable S9=2 and
make a bridge between terminal block 11 and 12, connect 0-10V reference signal to terminals
13 and 14, +V to terminal 13, GND to terminal 14.
- PROPORTIONAL mode with 4-20mA humidity probe:
This kind of functioning allows steam production in proportional mode, humidifier will regulate
automatically the production of steam as per ambient request. Enabling is provided by a 420mA humidity probe that regulates steam production, also allowing visualization of ambient
relative humidity, directly on humidifier display. To set the second level variable S9=1 and
make a bridge between terminal block 10 and 11, connect 4-20mA humidity probe signal to
terminals 8 and 9, signal RH to terminal 9, +V to terminal 8.

The proportional band Bp is the percentage value of humidity near to the set point, inside this
value the humidifier works in proportional mode. Example: if the proportional band is set on
default value 10% (-5% / +5% set point value) and the humidity is set to 50%, under 45% the
humidifier will works to 100% of steam production; over 55% of humidity the humidifier will
not produce steam. Between 45% and 55% the humidifier will adjust the steam production
optimally.

The proportional band Bp is a percentage humidity value around the set point; within this
band the humidifier works in proportional mode.
Example: if proportional mode is set to the default value of 10% (-5% / +5% with reference to the
set point) and humidity is set to 50%, then below 45% the humidifier works at 100% steam output;
above 55% the humidifier does not produce any steam at all. Between 45 and 55% the humidifier
will optimise steam output.
The steam percentage value Pr is the value the humidifier is able to reach at maximum output. For
example, leaving the setting at 100% on an ES6 rated at 6 Kg/h will give 6 Kg/h of steam output; if
the Pr setting is reduced to 50% the humidifier will produce 3 Kg/h at most.
The Pr variable is highly useful where water conductivity is poor and when you need to
make the most of the cylinder when it is nearing replacement; for further information
consult chapter 6 TROUBLESHOOTING of this manual at page 25.
The humidity duct set point (stC) is an humidity limit into duct. If the humidity in duct is higher the
humidifier stop steam production and restart when the duct humidity is less than StC-r0. Consider
an additional time delay (t1 on second programming level) before the steam production start again.
To gain access to the Level 1 programming menu proceed as follows:
- Press the (t) and (u) keys simultaneously and keep them pressed for a few seconds until the
first programming variable appears on the display.
- Release the (t) and (u) keys.
- Select the variable to be modified using the (t) or (u) key.
- When the variable has been selected it is possible:
- to display the setting by pressing SET
- to modify the setting by pressing the SET key and the(t) or (u) keys.
- When configuration values have been set you can exit the menu by pressing the (t) and (u)
keys simultaneously for a few seconds until the parameter shown before programming was
accessed (e.g. steam production or absorbed current) reappears.
- The new settings are saved automatically when you exit the configuration menu.

SINGLE HUMIDIFIER CONFIGURATION (default configuration)
The humidifier is set as "single" (MS=0) and works in autonomous way following the setting
given in S9 variable.
MASTER + SLAVE HUMIDIFIERS CONFIGURATION
In this configuration the humidifiers (up to 6 units) work as if they were a one unit producing
steam according to a common reference given from Master unit.
Moreover the Master manages the pecedences of de-concentration discharge or of various
humidifiers test (included its own) with FIFO (First In First Out) modality (one single deconcentration discharge at a time) thus ensuring continuity in steam production.
Connection between Master and slave:
The humidifier set as master communicates with various slave humidifiers through a serial
connection RS-485 between various 100-Master electronic controls.
Maximum connection length is not definite but it depends by cable quality and by relation
signal/noise. The length is fixed at about 500 meters.
The connection cable can be shieldless if distance is few meters in an electrically little “noisy”
ambient. For distances included between 15 and 100 meters it is possible to use a shielded and
twisted cable without particular features, whereas for connections over 100 meters it is
suggested to use, for example, BELDEN 8762 cable.
Communication line should be chain-type avoiding star connection.
The shield of used cable should be put to earth to one side. To avoid of lodging the serial
connection RS-485 in the same ducts (or hoses) of supply or power cables.

USER MANUAL
Functioning description:
The unit set as Master talks constantly with connected slaves through RS485 sending them the
information about quantity steam to produce (0-100%) and managing various units priorities
related to de-concentration discharges or test.
Functioning mode of Master/Slave whole of units is set only on Master through variable S9 as
the eventual connection of ambient humidity sensor, of duct humidity sensor, of 0-10V
reference signal, the ON-OFF enabling and desired humidity value setting.
Pr variable, that represents the steam production percentage to maximum running, is instead set
on every single unit.
The enabling lack (terminal blocks 1 and 2 open on 100Master card) generates the following
actions:
- On Master unit stops the same Master unit and all connected slave units (displaying OFF
blinking).
- On Slave units stops only the concerned slave unit (displaying OFF blinking).
Stand-by inserting through dedicated key, generates the following actions:
- If actuated on Master unit, it puts the humidifier in stand-by (stand-by led blinking) and
brings to 0 the steam production request of connected slaves.
- On Slave units stops only the concerned slave unit putting in stand-by the humidifier (stand-
by led blinking).
If the Master does not find a slave, after a 15 sec. timeout time, signals the problem with a
silencing alarm message (E7). This alarm does not stop the normal functioning. The slave
polling continues and, if the communication starts again, the error is reset automatically.
If the Slave has not polled by the Master within a 15 sec. timeout time, it considers the
connection interrupted and it leads the steam production to 0 disconnecting the electrodes and
signaling the fault with silencing alarm (E8). In the case the connection starts again, the error is
reset automatically and the system starts its normal working.
On set Slave (mS=1) humidifiers S9 variable is not considered, steam production follows in
proportional mode the information sent to RS485 by Master.
De- concentration discharge and test priorities management:
De-concentration discharge and diagnostic tests priorities are managed as follow:
Slave units, when polled, send the eventual discharge request to the Master that manages them
FIFO (first input / first output).
The Master waits for 3 minutes before giving the next enable to pending unit following the
FIFO priority; this procedure permits to currently discharging unit to start again the steam
production.
The Slave unit that has requested a discharge wait for Master enable for 45 minutes and when
they are passed the discharge will still be executed (Time out).

INITIAL START-UP
1. Check that default setting is compatible with signal connection; if it is different, set the
jumpers correctly before powering up as described on chapter 2.3 and 2.4.
2. Before powering up the humidifier check for correct connection of phases and signal type
(humidity sensor, N.O. contact or 0 - 10V); check for correct connection of the water mains,
excess water discharge and steam pipes.
If the mains water feed line consists of piping that might contain oily residues or other foamgenerating substances it is essential that it be washed out by letting water flow through for
several minutes.
3. To verify the absence of water loss internally the humidifier
4. Power up the humidifier.
5. The humidifier will carry out a water discharge for several seconds as it emits a prolonged beep.
6. At this point the humidifier is in STAND-BY mode; to switch it on press the ON/OFF –
STAND-BY key. On models configured in 4-20 mA PROPORTIONAL mode the humidifier
will display the humidity level detected by the sensor. For models configured in ON/OFF and
PROPORTIONAL 0-10V mode current absorption is displayed.
7. To function correctly humidifier needs enabling at digital input 1 with a free-voltage contact
(terminal blocks 1 and 2 on 100 Master card) indifferently from selected functioning mode.
If enabling is missing, the display will show OFF alternate to normal visualization
STEAM PRODUCTION
1. Set the required humidity by pressing the SET key. On PROPORTIONAL 4-20 mA
models increase the value with the UP key (if the setting is higher than that detected by
the sensor steam will be produced); on ON/OFF or PROPORTIONAL 0-10 V models give
ON/OFF enable.
2. Let the cylinder fill until the water starts to boil; empty the cylinder completely using the
MANUAL DISCHARGE key to prime the pump and repeat the procedure once or twice.
3. At this point the humidifier is operative and will work autonomously.

MAINTENANCE
To ensure working safety, correct functioning and an optimal output of EASYSTEAM humidifiers,
it is necessary to execute maintenance operations according to following instructions.
GENERAL SAFETY RULES
Every type of maintenance has to be done exclusively by experienced and qualified
technical staff, conscious about necessary safety.
Before starting any maintenance procedure, to proceed as follows:
1. If unit is out of service because of an alarm condition, to note the displayed error code.
2. To close the valve of water supply.
3. To put the humidifier in stand-by using the proper key and discharge completely the water
contained in the cylinder using the key “Manual water emptying” on Slim Controller (see chap.
3).
4. To disconnect the unit from the electric system sectioning the power input permanently
padlocking it on OFF.
5. To wait the cylinder and the humidifier have cooled or to use protection gloves.
6. Each unit element, if it is defective, has to be replaced exclusively with original spare parts.
MAINTENANCE INTERVALS
Following are indicated the maintenance operations to execute and their suggested frequency.
Being electrodes consumption and incrustations and solid deposits formation into the cylinder
variables according to the type of water (also with the same conductivity), it could be necessary to
modify these intervals.
To verify this need checking the deposits quantity into the cylinder; a quickly accumulation of
incrustations and deposits requires to increase the suggested maintenance frequency and/or the deconcentration discharges parameters variation.
To minimize residual formation on the bottom of cylinder it’s advisable to increase
deconcentration drain frequency reducing value of S2 parameter. This trick has
disadvantage of bigger water and energy consumption.

CHANGING THE CYLINDER
The only part of the humidifier subject to wear is the electrode cylinder. This wears
according to how much the machine is used or it is not possible to remove the internal
incrustations.
The EASYSTEAM range features stainless steel electrodes to maximise durability: however,
durability will largely depend on the quality of the water (conductivity and hardness) and on how
much the machine is used.
When the electrodes are worn the water level will rise excessively and trip the maximum level
alarm E1 several times: the cylinder must, at this point, be replaced.
Once you have checked that this alarm does not have other causes (see Chap. 6 – Troubleshooting)
change the cylinder. Proceed as follows:
NEVER CHANGE THE CYLINDER WITH THE MACHINE HOT AND WITH
WATER INSIDE IT. EMPTY ALL THE WATER FROM THE CYLINDER USING
THE MANUAL DISCHARGE KEY FIRST! IT IS COMPULSORY TO FOLLOW
THE INSTRUCTIONS REPORTED AT CHAPTER 7.2.
1. Open the humidifier by removing the front cover as indicated on page 14 (on OEM models this
is not necessary).
2. Unhook the frontal retainer spring from the upper steam flange and slide it off (Fig. 27, 28, and

USER MANUAL
GENERAL
Attainment of good steam distribution and therefore the desired humidity level in any
environment depends on two key factors: the quantity of steam introduced into that
environment and how it is distributed.
If, in fact, the steam is introduced into an environment in a heterogeneous manner there will be
zones of excessive humidity and zones that are too dry: this can lead to excessive condensation and
problems in controlling steam production due to the triggering of a “pendulum” feedback effect.
It is advisable to introduce steam by inserting a PEGO distribution lance in the air duct or in front of
a ventilation unit (where the steam is introduced directly into a room and not through a duct).
EXAMPLE OF IN-DUCT STEAM DISTRIBUTION
The PEGO distribution lance must be
inserted perpendicularly to the direction of
air flow in the duct.
To optimise distribution efficiency the lance
must cover as much of the effective air flow
width as possible
(fig. 41).

USER MANUAL
CONDENSATE RECOVERY
1. Independently of the type of application, a certain
amount of condensation will be generated inside the
distribution lance.
This condensation must be discharged so as not to
obstruct the flow of steam. If the lance is positioned
at a point higher than the humidifier and the steam
pipe has no water traps (siphon-like bends) then the
condensate recovery device need not be installed
(e.g. fig. 43).
Fig. 43
2. If the lance is positioned at a point higher than the humidifier and the steam pipe does have
siphon-like bends (e.g. fig. 44) it will be necessary to install a condensate recovery device. This
is a special hose that connects to the relevant cylinder manifold and carries the condensate
directly into the humidifier cylinder (fig. 45). The condensate can also be carried to a drain.
Recovery is effected by connecting the special hose (PEGO UMITUBODN10) to the 10 mm
diameter lance manifold. When routing the recovery hose from lance to humidifier or from
lance to drain it is necessary to create a water trap: do this by making a complete turn with a
minimum diameter of 200 mm; the siphon must also be filled with water prior to installation.
This will stop steam from exiting the condensate recovery hose (fig. 44).
Fig. 44 Fig. 45
3. If the lance is positioned below the humidifier as is generally the case on OEM humidifier
installations the condensate must be recovered by directing it into a drain.
